Chemical Structure
Description
2-chloro-1-(2,2-dimethyltetrahydropyran-4-yl)ethanone (CAS 77554-94-0), molecular formula C9H15ClO2 and molecular weight 190.67 g/mol, is a CATO reference standard with documented purity and traceability.
2-chloro-1-(2,2-dimethyltetrahydropyran-4-yl)ethanone (C9H15ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-chloro-1-(2,2-dimethyltetrahydropyran-4-yl)ethanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
